Jasp, another thing is that if you join the ABA then you are entitled to discount pump hire - it can be as much as 50% off. Plus you get the ongoing advice and support of a breastfeeding counsellor included! The ABA also have fantastic booklets for $5 each - the "Breastfeeding, Women and Work" and "Expressing and Storing Breastmilk" ones are really helpful for returning to work. They were a huge help to me.
